Diagnose carefully, I beg of you.

"I can feel your pain"
But can you really?
I highly doubt it.

You only see the surface texture.. the enamel of my personality.
Once innocently translucent,, inevitably growing more opaque day by day.

Have you any idea of the underlying dentin?
The abundant amounts of reparative dentin formed to prevent the cascade of harmful stimulants from reaching the pulp.

And what of the poor isolated pulp?
A traumatic experience could render it reversibly damaged, or -God forbid- irreversibly paralyzed.

You can veneer me all you want, but the dentin is still inside hard-headed and stubborn as ever.
You may bleach attempting to get rid of those discolored spots, and you'll find that as much as you overload hydrogen peroxide externally, internal bleaching rarely succeeds with me.
You can bandage the wounds with a thick layer of Calcium hydroxide, but the pulp still silently cries in agony.

The core of my being doesn't enclose a solitary layer... there are many.

Have you ever thought to dig deeper?
To treat the cause not only the symptoms?
Oh how I wish you would!
